I disagree. Advertising is a zero-sum game. If nobody advertised, every solution would be equally discoverable via search and word-of-mouth. It's only when some actors start advertising that the others must as well, so they don't fall behind. And so billions of dollars are spent that could have gone to making better products. It's basically the prisoner's dilemma at scale.
>If nobody advertised, every solution would be equally discoverable via search and word-of-mouth. No it wouldn't. If someone opens up a new restaurant a block away there's not going to be much word of mouth when it just opened, and even if they make a website, web search will prioritise the websites of existing restaurants because their domains have been around longer and have more inbound links.

2. Every one would be talking about it.
